Women are nearly the majority demographic in the world of gaming, but that hasn’t dampened the amount of offensive comments thrown their way. To help put an end to online gaming hate in general, League of Legends (LoL)—the world’s most played game—has turned to artificial intelligence. After learning what types of actions or comments were deemed abusive by its players, LoL put “machine learning” to work, weeding out and reporting offensive instances as soon as they happened—and the results were astonishing. Verbal abuse has fallen by 40% and, after being reported just once, 91.6% of players don’t act up again.
